About Ionic and Covalent Bonds虚拟实验室模拟
您是否曾经想过如何将原子结合在一起？在此模拟中，您将学习有关离子和共价化合物中原子键的基础知识，以及如何通过实验区分这些化合物。有了所有这些知识，您将帮助您的朋友分析他从炼金术士那里收到的两种神秘物质。通过测试其特定的物理特性，您将能够识别物质的性质。最后，您将学习离子如何形成晶格结构以及这如何影响化合物的特性。
Test solubility and conductivity
原子可以以多种不同的方式进行交互，从而具有特定的特定属性。在离子和共价模拟的第一个任务中，您的任务是选择适当的实验室设备以测试两种物质的溶解度和电导率。您将探索这些特性在离子和共价化合物中的不同。
Draw Lewis dot structures
在离子和共价键模拟的第二部分中，您将了解八位钟规则，以及如何将其应用于虚拟图纸活动中的Lewis Dot结构。您会发现，根据化合物和电子构型，可以多种方式形成共价键。您还将学习如何识别共价键中的孤独电子对。
Determine melting points
In the last mission, your task is to determine the melting point of the two substances by using melting point apparatus. You will explore how your results are connected to the ability of ions to form a lattice structure.
Will you be able to identify the two mysterious substances and help your friend cure his migraine?
